EXTENSION-TABLE.

Specification of Letters Patent.

Patented July is, 1909.

To all whom it may concern:

Be it known that 1, Ap rox G. WETTER- GREN, a citizen of the United States of America, residing at New York'cit in the county blew York, have invented certain new and useful. lm rovements in Extension-Tables, of which t e following is a specification, reference being had therein to the accompanying drawing.

This invention relates to an improvement in ex ension tables, the object thereof being to enable a small table to be more easily converted into one twice the size.

The invention consists essentially in the means whereby the table covers are shifted and transposed in changing the table from one size to the other; and also it consists in I size.

Fig. 3 is a top the arrangement, construction and combination of parts substantially as will be hereinafter described and claimed.

1n the annexed drawings, illustrating my 5 invention, Figure 1 is a top lan view of the main frame. of my improvec table with the top part removec. F 1g. 2 is a longitudinal section of the same on the line 2,2 of Fig. 1. Y plan view of the table when the parts are p aced so that the table may occupy itsextended position Fig. 4 is a longitudinal section of the table when the mechanism is in the position shown in Fig. 3. Fig. 5 is a cross section of the same.

Similarcharacters of reference designate like parts throughout all the different figures of-the'drawings.

The main frame of the tableconsists of a hollow rectangular body 1 of greater or less This main frame consists of the longitudinal sides 1, 1 connectedrby the end pieces 1", 1". The upper edges of the sides 1 are preferably provided with metallic plates 5 secured thereto by means of screws,

while the end ieoes 1 which connect the sides 1 have t eir upper edgestpreferably provided with metallic plates 6 at one end of the table, and 7 at the other end (see Fig. 1).

The said main frame 1 is supported on the usual 'legs 2 which may be attached thereto in any desired manner and may have any suitable form and size. The mainframe 1 is normally covered by the table top 12 as shown in Fig. 2, which is a single flat piece.

' z The common appearance'of the unextended table is shown not only in Fig. 2 in full lines,

but also in dotted lines in Flg. 1. Said top '12, however is adapted to be slid endwise for a certain distance when an extension of the table is to be effected, and then shifted to a position at right angles to that which it normall occupies when it covers the whole table, .a l as I shall presently explain.

3 denotes a horizontal bed or support which is substantially half the size of the rectangular frame 1 and is secured thereto, as shown in Fig. 1, near the plates 5 and 7., the other half of the rectangular frame 1 being left uncovered so that the extra leaf may be dropped therethrough into a boxing or upon a shelf placed Within the frame 1 to receive 1t.

On the stationary bed 3 are secured a groove 8 designedto receive a'sliding bar with which the table top 12; is provided. v

The rods 9' and 9 are rovided at one end with oppositely exten ing curved rods 10 and 10 which together constitute right and left guide tracks which guide the pins 18 and hence the shiftable top 12 while being turned around crosswise, thus holding it securely in such adjustment. The rod 9 is furthermore broken at the point 22 where it is formed with a curved and hooked extension 11. Oppo-- site to this curved and hooked extension 11 of the rod 9, the rod 9 is formed with an enlarged end having a curved edge 14. The

curved edge 14 corresponds in its curvature with the curved. edge of the extension 11, and these two curved edges, namely that on the rod 9 and that on the extension 11 of the rod 9, serve as-traoks for pins or rollers onthe movable and adjustable table top 12. The rods 9 and 9 may have any suitable width and sha e, andtheirinner opposing edges preferab y overlap the groove 8 tea smallextent, as shown in dotted lines in Fig. 1, so that the sliding bar which travels through the groove 8 may not escape through said groove, but may be held therein by the overla pin ed es of'the rods 9 and 9.

, Also, t e e ge o the curved track 10 and 1O similarly overlaps a small groove made he neath the same, as indicated in dotted lines, so that rollers or pins A on the table 12 may travel accurately in connection therewith.

Thetable top 12 is rovided centrally with a short bar 15 ivoted thereto by means of a pivot 16. Sai bar 15 has an enlar ed lower part which spreads at the ends an sides of, the bar 15 to form the flanges 19, as ndi cated in Figs. 1 and 2, which flanges operate beneath the overlapping edges of'the rods 9 and 9 when the bar 15 is traveling through the guide groeve 8. Furthermore; the table top 12 is provided with pins 18, 18, said pins projecting from a plate 17 which is set 1nto the top 12 opposite to the bar 15, the sameserves as a pivot for the bar 15, passing likewise throu h the inset plate 17;

he extended ends of t e bar-15 overlap the pins 18' when the bar 15 is in its central osition, as indicated inFi 2. Thus it wil be seen that when the fmr 15 is traveling through the maor part of its guide groove 8, the pins 18 likewise be traveling in the groove 8; but when the point is reached in said groove 8 where these pins 18 come op 0- site to the curved edges'14 and 11, the ta le top may be shifted on its pivot 16 and the pins 18 will pass to the opposite sides of the groove 8, one moving through the groove'22 and alon the curved edge 11, and the othermoving a ong the curved edgelfi, said movepin 16 which ment continuing until one pm '18 strikes against the shoulder 14 at the end" of the track 14, and the other pin 18 strikes against the shoulder 11 at the hooked end of'the' curved edge 11. The table top 12 is furthermore provided with a pair of headed ins or rollers 20 which when the table-top is in its normal unextended position, as shown in v Fig. 2, enter receivin notches 21, 21 in the plate 7 at one end of the frame 1. At the same time that these headed pins or rollers 20 enter then'otches 21, a spring bolt 23 arranged in connection with the opposite end 1 of the frame and working t rough the plate 6 engages a recess 24 in the 12, and thus the tabletop is ke t firmly in position. When it is desired tos 12 for the urpose of increasing the'size of the table, t e-spring' bolt 23 ma be withdrawn from the top-i12 by simply aying hold of the releasing catch 25', asshown in Figs. 1 and 2. The top 12 furthermore is provided with a pair of headed pins or rollers 26, 26 which operate on the curved track 10, 10 when the to 12 is being shiftedfrom one position to t e other.

Inside of the main frame 1, I lace a horizontal tiltable leaf-receiving she f 27 which is.

preferably flanged at the edges, as at 30, and 1s designed to support the folding leaf which is used to enlarge the size of the table when it is to be extended. Said folding leaf is designated 13, and when extended is of the same size as the per1nanenttop-12. The

moved from said 0 en part when needed to l extend the size of t e table. The inner op she position shown in fu table top,

ift the topother pins which 006 .of'varying therefrom if be folded for the purpose of occu-1 in pro er relative posing faces of the longitudinal sides 1*, 1f

of the main frame 1 are provided with in-" clined grooves 28, 28, there being two on each of the sides 1, and the grooves at the op osite ends of the table being oppositely inc ined to each other. The grooves at one end of the table are also somewhat longer than those at the other end, though this is a matter of taste and can be changed in differ ent tables. The shelf 27 is provided with lateral pins 29, two on each edge, which enter the rooves 28. It will thus be seen that the 27 may occupii either the horizontal lines in Fig. 2;, or that shown in dotted lines in the same figure, and that it is shiftable and ti-ltable by easily laying hold thereof, inasmuch as the lateral projecting pins 29 loosely engage the in-' clined grooves 28 and ermit of such a movement. As the incline grooves 28 which are farthest from the open end of the table drop lower than the other or forward grooves, that is to say, as they come nearer to the-lower edge of the sides 1, it is obvious that the shelf 27 will dro lower at that end than at the forward en when it is-desired that it should do so. This is in order that the folded leaf 13, which is'lying upon the shelf 27, may have one end'thereof throw n upward into the open part of the table frame where it can be more readily grasped by the hand for the purpose of "removing it from its shelf and 'fting it out of the frame for the purpose of placing it in position on the top of the latter.

I ha'ves'tated that the inclined grooves 28 at one end oflthe table run' lower down and nearer the bottom edges of the sides 1 than dobtlhe similar grooves at the other end'of the ta e.

"29 on the shelf 27 which cooperate with said grooves that run nearest to t e lower edge of I may say also that the lateral pins the sides 1 a are set somewhat above the bottom of the shelf 27 and somewhat above the erate with the grooves at the other end of t e table. This is a detail of construction, however, to which I do not wish to be confined,- although Irealize that in actual practice'the best results in the -rnanipulation.of the shelf are secured by this placing of-the pins; but I reserve the liberty desired.

, I When the permanent top 12. is in its unextended position, .as shown in Fig 2, the

headed pins orrollers 26 will engage with the lates 5,"'as shown in Fig. 1,sa1d lates proectinggslightly over the edges of t e sides 1 on which they aresecured, as indicated in dotted lines in Fig.

ment of the top and in keeping a l the parts osition.,; ,The plates 5 are.

provi edjwith in, ents 34, wheretheheaded pins or rollers 26 can easily be disenga ed rom the plates 5 whenever the table ista en apart. a

Supposing the top 12 to occupy thezunextended position shown in Fig. 2, and that it is desired to extend will be to disen age bolt 23 from the top 12 by depressing he handle 25. The to 12 will then be pushed in the direction of the arrow in Fig. 1, which movement will result in disengagm the headed pins or rollers 20 from the note es 21, and 'in causing the bar 15 to slide throu h the groove suntilthe pin 18 sto s by strifiing against the 'end of'the table rame. At this tlme the to 12 can be shifted upon itspivot 1,6 which WI pins 18 to travel on the 14 as already explained. At the same time one of the rollers or headedpins 26 willpass out through the slot 31 cut in one of the plates 5,7while the other headed pin or roller 26 will travel on the curved'track 10 toward the center of the table. In other words, the parts will assume the various ositions shown 1n dotted lines at the left in ig. 3, where the top 12 is in a position at right angles to that which it occupies in Fig. ,2. The folded leaf 13 may now be withdrawn from the shelf '27 by tilting said shelf into the position shown in dotted lines in Fig. 20, as already ex plained. After the leaf has been unfolded,

cause the 1t will be placed upon the top of the table frame alongside of the top 12. In {placing it the angle pins 33 on the underside of the leaf 13 will be caused to engage the overlapping edges of the plates 5 on the top of the frame, and likewise certain headed pins or rollers 35 on the underside of the leaf 13 will be caused to engage notches 32 inthe plate 6, and also the bolt 23 may be caused to enter a suitable opening in the underside of thegleaf 13. In this way the leaf 13-is held in position and the table top being extended by the use of this leaf in the manner I have explained will be twice as large as before. A reverse operation in the handling of the various parts may take place whenever it is desired toc ntract the size of the table to the normal, inewhich case the leaf .13 will be again folded and restored to its idle position on the shelf 27.

Having thus described my invention, what the table, the first act a curved edges 11 and provided with connecting rm at u desire to secure by Let tracks at the ada ted to beengaged by said pins when the tab e-t p is turned crosswisefor the purpose of race ving an extra leaf.

2. In an extension table, thecombination with a main frame proyid'ed'with a straight guide-Way having right and left curved tracks at one end, a table-top having a sliding bar pivoted thereto and working in the guide-way and having also devices to engage the curved-tracks, and an extension leaf vided with looking devices and adapted to placed upon'the frame after the table-top as been shifted into its crosswise position. 3. In an extension table, the combination with the mainframe having 010' ositely in 'chned grooves on opposite inner aces of said frame, of a shiftable top arranged to leave an opening in the table when shifted, a leaf receiving shelf having lateral pins that en gage said grooves so that the tilted and its contents lifted opening.

4. In an extension table, the combination with a main frame having central guiding; tracks forming a straight guide groove and provided with rightand left curved tracks on opposite sides thereof at. one end, and a shiftable table-top carrying a flanged sliding bar having a pivotal pin working in said guide groove, locking pin devices which engage the separate curved tracks, means for stopping the pin devices, and a folding leaf and retaining de attaching it to the main tabletop surface can be through. said.
